Hmm for some reason I can't open this PNG? Any ideas?
How do operating systems know what kind of file it is? (It's not just the ending!
Make sure to submit the flag as picoCTF{XXXXX}
Do file flag.png to find the actual filetype.
However, most image viewer software should be able to open the .png file without any problem.
If this doesn't work change the file extension to .jpg
